Backwashable trickle biofilter biotrick tower biofiltration system

The trickling biological filter is a compartmentalized and sealed biological filtration device. It is filled with biological filter material. Water is sprayed down from above to form a large amount of humid and porous environment under sufficient oxygen
.r conditions. Generally, most popular biological filters on the market use this method for filtration. . But they all have one shortcoming: they cannot be backwashed. When
.r There are too many suspended solids in the water attached to the biological filter material and the amount of dirt formed by the aging of the biofilm increases. Here there is a way to clean out these aged bacteria and suspended solids. At this time, a backwash procedure is required.
In order to meet this need, Guangzhou Lanling Aquarium Equipment Co., Ltd. has developed a backwashable trickle-type biological filter. The space between its upper and lower cells
.r is sealed. Under normal circumstances, water flows down from above and the air is pressurized from below through an air pump. The air and water are fully mixed in the biological filter material
.r Combined with the characteristics of the large specific surface area of the biological filter material
